Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Mon May 5 2025

Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 140W. The following
information is based on satellite imagery, weather observations,
radar, and meteorological analysis.

Based on 1200 UTC surface analysis and satellite imagery through
1500 UTC.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

The monsoon trough extends from 11N75.5W to 11.5N91W to 07N125W.
The ITCZ extends from 07N125W to 07.5N134W to beyond 05N140W. 
Scattered moderate to strong convection is noted from 02N to 13.5N
east of 96W, from 05N to 11N between 96W and 125W, and from 05N 
to 09.5N between 130W and 140W.

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A surface trough, remnants of a cold front, extends across the
southern Gulf of California from interior portions of northern
Sinaloa to a 1009 mb low center located east of Cabo San Lucas
near 23N108W. 1030 mb high pressure continues well NW of the area
behind the dissipated front. Overnight satellite scatterometer 
data captured westerly gaps winds impacting the entire Gulf of 
California with fresh to strong winds in each of the gap areas,
and strongest winds to 30 kt across north and central portions.
Winds across these areas have likely diminished slightly in the
past few hours. Seas are 4 to 6 ft across north and central 
portions and 4 to 5 ft elsewhere. Across the Baja offshore waters
fresh NW winds and rough seas 8 to 14 ft prevail across the
waters north of Cabo San Lazaro, and seas of 6 to 7 ft elsewhere
across the Baja and Mexican offshore waters. Strong NW winds are
along the coast off of Cabo San Lucas, raising localized seas to
8 ft there.

For the forecast, the surface trough will continue to move SE 
across the southern Gulf of California today and dissipate 
tonight. Fresh to strong westerly gap winds will persist across 
the northern Gulf of California through later this morning. Fresh
to strong winds and seas to 8 ft will continue off Cabo San 
Lucas through tonight. Large NW swell will reach the waters off 
Cabo San Lazaro today, reach the Revillagigedo Islands Tue, and 
subside Wed evening. Light to gentle breezes, except moderate to 
fresh NW winds off Cabo Corrientes, will persist elsewhere off 
southern Mexico through Fri night. 

...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, 
AND WITHIN 750 NM OF ECUADOR...

Weather remains unsettled across the waters east of 90W as 
showers and isolated thunderstorms associated with the monsoon 
trough also impact the coastal waters from Guatemala to Panama 
and Colombia. This shower activity is supported by the inflow of  
moderate to locally fresh SW to W winds across these offshore 
waters. A weak pressure gradient elsewhere is resulting in light
to gentle winds. Seas of 5 to 7 ft primarily in SW swell are 
ongoing across the offshore waters between Ecuador and The 
Galapagos as well as the Central America offshore waters.

For the forecast, gentle to locally moderate breezes will 
persist across the waters off Central America, Colombia and 
Ecuador, with primarily moderate SW swell through the middle of 
the week. Looking ahead, large SW swell is expected in Ecuadorian
waters Tue night through Thu. 

...REMAINDER OF THE AREA....

A 1030 mb high center is located north of the area near 35N140W,
and extends a ridge south and southeastward across the regional
waters W of 110W. Strong to gale-force northerly winds offshore
of California become fresh to strong south of 30N between 120W
and 130W, to the north of 28N. Seas across these waters are 9 to
14 ft in northerly swell. Elsewhere south of the ridge Fresh to 
locally strong N to NE winds prevail west of 120W, southward to
the ITCZ along 07N-08N. Seas there are 6 to 9 ft in mixed swell.  
Moderate or weaker winds and moderate seas are noted elsewhere. 

For the forecast, strong high pressure north of the area will
persist today, then begin to drift SE and weaken through Wed,
ahead of an approaching cold front. This will maintain fresh to 
locally strong N to NE winds and building seas through Tue, with 
the strongest winds and highest seas occurring east of 130W. 
Winds and seas will diminish Tue night into Wed.
